Description
Give your winter tires real grip on ice with Ugigrip TSMI #12 tire studs. Each stud carries a tungsten carbide pin that bites into glare ice and hard-packed snow, helping drivers stop, start and steer with more confidence.
This is the TSMI #12 size, part code 9-11-1, for passenger car, light truck and SUV winter tires with pre-molded #12 stud holes. Go with the TSMI number the tire maker recommends, and if it is not marked, measure the hole depth: as a general guide, a hole that gauges about 12/32" deep calls for the #12.
Studs install with a #10 passenger tire stud gun, sold separately, and seat best in new tires with clean stud holes. Wet each hole with a little water before setting the stud, and a correctly seated stud shows only the carbide pin and a sliver of the body above the tread.
This listing includes one box of 1,000 TSMI #12 tire studs. Stud laws and seasons vary by state and province, so check local regulations before installing.
